 Effect of ethanol–diesel blend fuels on emission and particle size distribution in a common-rail direct injection diesel engine with warm-up catalytic converterHwanam Kim and Byungchul Choi Renewable Energy, 2008, vol. 33, issue 10, 2222-2228 Abstract: In this study, the exhaust gas from a common-rail direct injection diesel engine was investigated both upstream and downstream warm-up catalytic converters (WCC). Three different types of ultra-low sulfur fuels (ethanol–diesel blend, ethanol–diesel blend with cetane improver and pure diesel) were tested in this study. The objective of the work was to study the engine performance and the formation of THC (total hydro carbon), CO (carbon monoxide), NOx (nitrogen oxides), smoke and PM (particulate matters) when using these fuels. THC and CO emissions of the ethanol–diesel blend fuels were slightly increased, and about 50–80% mean conversion efficiencies of THC and CO on catalysts were achieved in the ECE R49 13-mode cycle. Smoke was decreased by more than 42% in the entire ECE 13-mode cycles. From the measurement of scanning mobility particle sizer (SMPS) for the particle size range of 10–385nm, the total number and total mass of the PM of the ethanol–diesel blend fuels were decreased by about 11.7–15% and 19.2–26.9%, respectively.
